TO ALL WI-IOM I'l MAY CONCERN Be it kuownthat we, MosELEY S. CURTIS andWrLLniM D. Tnwnsunr, both of the city, county, and State of New York,have invented a certain new and useful Improvement in Hose and otherCouplings, of which the following is a full, c lear, and exactdescription, reference heilig had to the accompanying drawing, formingVpart of this specification,and in which- Figure 1 represents alongitudinal section of a hose-coupling constructed according tio ourimprovement.v

Figure 2, a transverse section thereof through the line xa; and

Figure 3, a sectional plan of the female coupling through thev line z zin iig. 1.

Like letters indicate like parts throughout the several figures. -v

This invention relates to what is usually known as Gaylordshosecoupling, in which the male and female butts are so combined with aninterposed'elastic packing-ring as that, by the application of forceto'one side only of the coupling, said butts are drawn together orreleased to establish or break the connection as required, and whichaction is `produced by-means of a radial outside screw formed with abevel end arranged in the one butt, and working against a bevelled ringon the other-butt, in connection with a bevelled projection opposite tothe screw in the same butt as the latter, and bearing `against: thebevelled ring of the inside butt', andV the nature of our inventionconsists in a novel combination, with a bevelled ring or formation onthe male' butt, and bevelled projection inside'tlie female butt, of asliding bevelled-edged b1ock,voperated by a screw from the outside, andthat serves toV tighten up or release the coupling without turning orguiding on'the bevelled ring of the inside butt, and withoutlongitudinalplay of the screw, thereby lessening the protuberance outside of thelatter. And said invention further' consists in a peculiar constructionor arrangementof certain details for effecting such action. `This ourinvention, by a suitable modification of the butts, is applicable aliketo pipe as to hose-couplings and connccting-shafts. As represented inthe drawing,-it is shown as. applied to a hosecoupling. i Y

Referring to the accompanying drawing, A represents the male, and B thefemale butt. C is the interposed soft or elastic pacling. The male buttA is constructed with a bevelled ring or formation,'b, and the femalebutt with a reversely bevelled formation or partial ring, lc. Through oron the female buttB is anozzle, D, of such congurntion on the inside asto snugly receive within it, so ns to be incapable of turning therein, asquare or other shaped sliding-block, E. To prevent leakage, thissliding-block may be fitted with4 a packing, d. It is bevelled on itsedge, that, by means of a screw-cap,E is made to bear against thebevelled ring formation b of the male butt. The screw-cap F is providedwith a screw-shank or` pin, e, that tits into afemale screw 01 thread inthe block E, and so that by turning the screw-cap to the right or left,the block E is lworked radially in or out to tightenl up or release thecoupling by causing its vbevelled edge to bear on or off the bevelledring b. To effect thisA action the screw-cap F has a fixed rotation onthe nozzle D, which 'may be accomplished by screwing the cap on Ato asplit ring,f, fitting a groove in the nozzle, and so as to be capable offreely turning therein with the cap; a pin, s, serving to hold the capand ring together. Another pin, g, projected through one side of thenozzle, and fitting into a groove, i, in the block, restrains the latterfrom being worked below a proper point orldistanc'e. l V

From this description it will be observed that as the block E does notturn in its socket, and presents a long or broad bearing on the bevelledring of the male butt, there is no grinding action on the latter, andthat a. long effective resisting surface is obtained; also, that thescrew which operates the block has no longitudinal' motion whereby itsprotuberance or that of its cap on the outside is diminished.

What we claim as our invention, and desire to secure by Letters Patent,is-

l. lThe combination, with the bevel rings orformations and c on the maleand female butts, ofthe beveledged sliding-block E, when saidsliding-block is prevented from revolving, and operated by means of ascrew, restrained from longitudinal play, substantially as specified.

2. The combination of the screw-cap F, screw e, and sliding-block E, foroperation in connection with the butts and their bevelled rings orformations, all constructedand arranged essentially as herein set forth.
